SPINNING-RING. FRAME.

SPECIFICATION forming part of Letters Patent No. 787,087', dated April11, 1905.

Application tiled October 10,1904. Serial No. 227,863.

To /17/ /I'zomy if nmy/ cmi/ecrit:

lie it known that l, Ouvrir. Dunas, a citizen of the United States,residing at Fall Hiver, in the county of Bristol and State of.llassachusetts. have invented a new and useful Improvement inSpinning-Machines, of which the following is a specilication.

rl`his invention has reference to an improvement in spinning-niacinnes,and more particularly to an improvement in means for oiling theliftevrods of spinning' or similar machines.

ln s1inning-frames or similar machines the lifter-rods are supported inhearings in the front rails of the machine and are reciprocated throughthe hearings hy the lifter-arms, which in turn are operated hy thehuilder motion to reciprocate the ring-rail hy the lifter-rods in theusual way. As heretofore constructed the hearings for the lifter-rodswere usually' vertical holes in the Yfront rails used without oil,therehy causing friction and requiring increased power to runtheinachine. lf oil were inadvertently used in these hearings, lint fromthe machine would collect on the oiled rods, clog up the hearings,causing' them to hind` and prevent the accurate reciprocating movementof the ring-rail.

'l`he ohject of my invention is to provide means for properly oiling thehearings of the lifter-rods of spinning-frames or similar maehines.

further ohject of my invention is to improve the construction of thehearings for the lifter-rods of spinning-frames or similar machines.therehy preventing lint or other extraneous suhstances from entering theheal'- ings.

My invention consists in the peculiar and novel construction of thehearings for the lifter-rods of spinning-frames or similar machines, anoil-well connecting the hearings, and adjustahle cone-shaped caps on thehearings` wherehy the hearings are kept properly oiled and free fromlint or other foreign suhstances, as will he more 'fully set forthhereinafter.

Figure l is a front view of part of a spinning-frame, showing alifter-rod provided with my improved hearings and oiling device;

l l l l I and Fig. 2 is a vertical sectional view taken on line X X ofFig. l, showing the construction of the hearings, the oil-wellconnecting' the hearings, and the cone-shaped caps on the hearings.

ln the drawings, f f indicate the front rails, the ring-rail, e alifter-rod, and 1/ a lifterarm, of a spinning-frame. 'lhe front railsfl`a, have the vertical holes u' f/ and the sct-holts u ffii, as shown inllig. 2.

w i indicate the hearings, ff the coneshaped lint-proof caps` f/ theoil-well connecting the hearings, /l /z the outer felt packing-rings,and f i the inner felt oiling-rings, of my improved oiling device.

'lhe hearings l r each have thevertical hore l for the liftern'od e andthe enlarged screwthreaded head di, in the end of which is thedepression c" for the packing-ring The hearings extend through the holesn' u' in the front rails. in which they are secured hy the set-holts o."n, as shown in Fig.

'lhe caps ff each have the cone-shaped top j", in which is the holefi'for the lifter-rod e and the inuersurfzwef", hearingon the packing-ring'.lhe caps f f are :uljustahly secured to the hearings hy screwing' themon the heads ,7i and held in the adjusted position hy theset-sere\vsf"lf". 'lhe cone top of the caps extends outward from thehearings and closely lits the lifter-rod, forming a knife-edge forscraping otf lint or other foreign suhstances which may collect on therod.

'lhe oil-well ,f/ consists of a tuhe surrounding the lifter-rod andhaving the oilhole y/3 and the screw-threadinl ends (/i f/i. ',lhe tuhc,r/ is held in position hetween the front rails 1,/ 1/ hy thescrew-threzuled sleeves g" which are in screw-tlnead engagement with theends ,f/x ,f/i of the tuhe ,r/ and are supported in position hy theinner ends of the hearings c (f. which extend into them, as shown inFig. 2.

'lhe felt packing-rings /i /f are each held hetween the depresion e inthe hearings and the inner surlacef of the caps and prevent lint orother foreign suhstances from entering the hearings, and the feltoiling-rings f f' are each held hetween the inner ends of thc hearings ee and the ends of the tuhe lIO In the operation of my improved oilingdevice for spinning-machines the lifter-rod c and the bearings e e areoiled by the reciprocating movement of the lifter-rod through the oil-Well g, which is supplied with oil through the oil-hole g2. Thecone-shaped caps f f prevent lint or other extraneous substances fromentering the bearings by scraping olf any lint or foreign substancewhich may have collected on the oiled lifter-rods outside o1c thebearings, and the caps f f are adjusted by turning them on the bearingse e to tighten the packing-rings t and secured in their adjustedposition by the set-screws f4 f1.

It is evident that the cone-shaped caps ff may be constructed of sheetmetal, if desired, and adjustably secured to the bearings e e in anyWell-known Way Without materially affecting the spirit of my invention.

What I claim as my invention, and desire to secure by Letters Patent,isw

l. The combination with the front rails and lifter-rod of aspinning-machine, of bearings for the lifter-rod, means for securing thebearings in the front rails, cone-shaped caps on the bearingssurrounding the lifterrod, and means for adjustably securing the cap tothe bearings, as described.

. 2. The combination with the Jfront rails and lifter-rod of aspinning-machine, of bearings for the lifter-rod, means for securing thebearings in the front rails, cone-shaped caps surrounding the lifter-rodon the bearings, felt packing-rings intermediate the ends of thebearings and the inner surface of the caps, and means for adjustablysecuring the cap to the bearings, as described.

3. rlhe combination with the front rails and lifter-rod of aspinning-machine, of bearings for the lifter-rod, means for securing thebearings in the front rails, a tube surrounding the lifter-rod formingan oil-Well connecting the bearings, felt rings intermediate the ends ofthe tube and the bearings, cone-shaped caps surrounding the lifter-rod,felt packingrings intermediate the ends of the bearings and the innersurface of the caps, and means for adjustably securing the caps to thebearings, as described.

4. The combination With the front rails and lifter-rod of aspinning-machine, of the bearings e e, the cone-shaped caps ff, theoil-Well g connecting the bearings e e, the sleevues g4 g4, the feltpacking-rings /L /L intermediate the outer ends of the bearings and theinner surface of the caps, the felt rings z' z' intermediate theoil-Well g and the inner ends of the bearings, means for adjustablysecuring the caps to the outer ends of the bearings, and means forsecuring the bearings in the front rails, as described.

In testimony WhereofI have signed my name to this specification in thepresence oftwo subscribing witnesses.
